It is endemic to Sri Lanka with unique flavour characteristics compared to green coconuts, which are available in other coconut-growing countries. King coconut cultivation in Sri Lanka has been estimated as 2.20 million palms (DCS, 2005) and mainly concentrated in Kurunegala, Gampaha and Galle districts. King coconut is a drupe, which is enclosed with an edible liquid endosperm (water) and a solid endosperm (kernel).
